Fertilizer special for Prunuspersicacv .Fei Cheng

Abstract

The invention discloses a fertilizer special for Prunuspersicacv .Fei Cheng. The fertilizer is composed of five elements which are N, P, K, Ca and Mg, octyl phenol polyoxyethylene ether (OPE) and benzothiadiazole (BTH), and the content of N is 4.2 mM, the content of P is 2.3 mM, the content of K is 1.4 mM, the content of Ca is 1.5 mM, the content of Mg is 0.7 mM, the content of OPE is 15 mg / L, andthe content of BTH is 120 mg / L. The fertilizer has the beneficial effects that: by spraying the fertilizer, uniformity of the internal hardness and brittleness of the fruits can be improved, in otherwords, the whole fruits are mature, and the content of soluble solid matters and the overall sensory evaluation are improved; in addition, due to the fact that the octyl phenol polyoxyethylene ether(OPE) and the benzothiadiazole (BTH) are introduced to serve as a surface active agent and an enzyme resistance inducer, the fertilizer utilization rate is further increased, the LOX enzyme activity of the fruits is improved, and therefore the SSC and the fragrance of the fruits are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for Feicheng Buddha peaches. Background technique [0002] As one of the high-quality domestic fruits, Feicheng peaches are large, sweet, juicy, rich in aroma, and have a unique flavor. They are well-known at home and abroad and have a long history of cultivation. Among them, the ripeness of the belly suture of Feicheng peach and its opposite sides is too big. The belly suture matures early, while the opposite side matures late. The difference is so obvious that the flesh has softened and soaked at the belly suture. Soft, sweet and delicious, but the opposite side of the abdominal suture is still unusable, hard, brittle and tasteless like a radish, if the harvest of Feicheng peaches is delayed, it will cause browning, rot and fruit drop at the abdominal suture, making Feicheng peach The quality of Feicheng peaches cannot be guaranteed, and a large number...

AI Technical Summary

Problems solved by technology

Through the analysis of soil sampling in Feicheng area, it is found that the range of Ca / Mg in the soil is 12.5-25.29, which obviously exceeds the recommended range of 1.2-6.2 for Buddha peach. The high calcium-magnesium ratio makes the antagonistic effect obvious, and the soil in this area is continuous The extensive application of phosphorus fertilizer for many years also reduces the activity of magnesium in the soil solution. It can be seen that although the Buddha peach is a special product in Feicheng, with the changes in the soil composition in recent years, the cultivation of Buddha peach requires more precise fertilization operations, so as to ensure the quality of the fruit. quality guaranteed
